Jumping Spider Life Cycle

Life cycle documentation for a Viciria sp. jumping spider family I came across recently, in chronological order: from eggs, to newly hatched to after first molting (first instar). Not a complete one, I know, but I am more interested in the initial stages.

All images taken with 40D, Canon MP-E 65mm f/2.8 1-5X Macro Lens ,Canon MT-24EX Macro Twin Lite Flash and DIY Concave Diffuser.

Some of the eggs had hatched. Some hadn't though. Click image to view bigger version.

Green, translucent and cute :)

A higher magnification shot of the cuties. Approx. 2X life size i think.

Even closer, approximately 4X life size.

First instar Viciria sp. spiderling.

This spiderling had already molted! The eyes were developed. There were hairs on the cephalothorax. The baby fat was gone and the abdomen was much slimmer compared to unmolted ones.

The exuvia. You will see these in some of the following images.

I wondered why mom was still around even after the spiderlings had molted. But I think i found the answer in the next image. Pardon the poor IQ. From a point and shoot camera.

The answer can be found in this image.

First instars (molted once) Viciria sp. spiderlings. Not all though. If you look carefully, you will see that two of them hadn't molted yet! Can you point out which two?
